According to the Casual Games Association, there are over 200 million casual game players worldwide. One genre of casual game is the hidden object game. Mystery Case Files: Return to Ravenhearst by Big Fish Games is one example. You are presented with a picture full of images and a list of items you must find. As you click on the item in the picture, it is crossed off the list. When you find the last item, you progress in the story to the next location or puzzle.
